  • Warning Status: When displayed, a condition code is active. Review conditions on the left screen.
  • SD Card Status: Displays approximate used capacity by filling the outline <25%, 25-50%, 50-75%, >90%. A slash indicates the card is not mounted.
  • Cellular Network Activity: Displayed when active.
    • Blinking: Connecting
    • Solid: Communication with LI-COR Cloud
    • Off: Idle
  • Querying SDI-12 Sensor: Displayed when communicating with an SDI-12 sensor, absent otherwise.

Home

The home screen is displayed after starting up. It presents general status information:

  • System Uptime: Days, hours, minutes, seconds since last restart.
  • SD Card: Status and capacity.
  • Messages: Number Sent, Number in Queue.
  • Battery: Voltage at the battery connector.

Messages

The interface may present a messages as it boots up and during normal operation. These messages may require an interaction to dismiss or they are dismissed automatically.

Message Indication
Sensor config data needed. Please wait for cloud session to complete.

Configuration tool needs information from LI-COR Cloud.
Unsupported sensors have been removed Configuration tool concluded that at least one attached sensor is not supported by the IoE Module or LI-COR Cloud yet.
SDI-12 is in use Cannot perform SDI-12 network scan while measurements are being taken.
Please wait while downloading data Actively receiving data during cloud session.
It is now safe to remove the card SD card dismounted and ready for removal.
Mounted "SD CARD" Displayed after every startup, this message can be dismissed or ignored.
Formatting card… If you attempt to mount an SD card belonging to another IoE module, you will be prompted to un-mount or format it. If you choose format, you see this for a several seconds.
Card formatted and mounted for use Format was successful.
Format FAILED. Card dismounted Format was not successful. You could try again. If it fails a few times, try a different card.
Waiting for SD card to be idle before dismounting… Displayed if attempting an un-mount action or soft power-down while the IoE Module is writing to the card.

System Information

Press the left arrow key () once to view system information, starting with Conditions.

Conditions

Under Conditions, you'll see a table of classes and conditions. Normally the table is empty, but it will display useful information if something should be brought to your attention, or if something has gone wrong (see Conditions and classes).

With the exception of conditions that are triggered during the startup cycle, conditions will remain visible on the display until cleared, even if the issue is resolved. This is intentional so that operators can observe conditions that have been triggered previously. Press Select to clear past conditions and show only current conditions.

Figure 7‑1. The Conditions table informs you of issues. Several conditions will be displayed momentarily as the IoE Module starts up and establishes the cellular connection, GPS information, and communication with LI-COR Cloud.

About System

Press the down arrow key () to access system information. The About page gives details about the hardware and software, including the Reg Key and device details.

The client ID is given under the about screen.

You will need to scroll down to view everything in the list.

  • Serial: Device serial number1.
  • Firmware: Firmware version currently running.
  • FW ID: Firmware ID.
  • Boot Cnt: Number of times booted.
  • Modem: Modem ID.
  • Mod. FW: Modem firmware version.
  • Mod. SN: Modem serial number.
  • ICCID: Integrated Circuit Card Identifier (ICCID) from the SIM card1.
  • IMEI: International Mobile Equipment Identity (IMEI) a unique numeric identifier for the IoE module1.
  • Reg Key: A unique identifier for client services on LI-COR Cloud1.

QR code

The QR code encodes information about the IoE module, including the device serial number (SN), SIM identifier (ICCID), International Mobile Equipment Identity (IMEI), and the Reg Key (KEY).

Compliance

Some details about legal conformity are presented here.

SDI-12 Setup

The SDI-12 page is to add sensors to this IoE node. Follow the steps on the display and see Powering on for more details.

The instructions on screen guide you through the SDI-12 sensor setup.

UTC Offset

Press left () again to access time settings, where you can apply an offset to the UTC time provided by the GPS receiver. Use the arrow keys and press SELECT to apply.

The interface presents options to set the time zone.

IoE Module status information

From the home page, press right () to access status pages, starting with Power.

Power status

Information related to the battery, solar power supply, system voltage, and SDI-12 power output.

Power status information is one press to the right.
  • Battery: The battery voltage (V) is given, as well as current (A) used.
  • Solar panel: The solar panel output voltage (V), measured at the circuit board (normally is <25 volts).
  • System: System voltage.
  • SDI-12: Voltage (V) delivered and current (A) used by SDI-12 sensors. Press right once to select an option to Turn Off or Turn On the SDI-12 power.

Modem status

Information about the cellular network, including signal strength and the service provider. Press SELECT to send a test message, which pings the network connection and returns either a success (PASS) or failure message, along with details.

Modem status information presents information and test options.

GPS status

View information about the GPS signal, including the recorded position, altitude, HDOP (horizontal dilution of precision), number of satellites, and the date of the last fix.

GPS status given

SDI-12 status

Status of connected sensors. Press SELECT and the module will scan each SDI-12 channel and return information about connected sensors.

SDI-12 sensor status and testSDI-12 sensor check results.

  • First line: Sensor manufacturer and model, as reported by the sensor.

    • For the LI-710, expect something like LI-COR LI-710.
    • For the Stevens HydraProbe, expect something like STEVENSW 056012.

  • Second line: Serial number.

  • Third line: Most recent communication or data request.

    • Last seen YYYY-MM-DD at HH:MM:SS
    • Not pinged yet indicates that the IoE Module has not communicated with the sensor yet. This message should clear shortly.

Powering off

To power off the IoE Module, short press the power button. In the pop-up message, select Yes and the press Select.
